Be it known that I, Jona V. Ausma, a citizen of'the United States,residing in the'city and county of Los. Angeles and State of California,have invented a new ments, whereby t e oils and fats may be and usefulFilter for Reclaimin Crankl Case Oil and Other Mineral ils and AnimalFats, of which the following is a specification. j

The present invention relates to an i-m. proved filter for reclaiminoils and fats, and particularly for cra -case oil, landcomprehendsfiltering elements in combination with agitatin elements andheating elecleansed and restored to their original condition.

The invention has for its object to provide an improved means foragitatingthe owmaterial during the preheatin'gste and other improvedmeans for agitating t e ma# I terial during the final filteringstep, andinlnents which are to cludes means for producing a predeterminedpressure within the filtering parts, means for agitating the materalunder pressure, and means for controlling the flow of the maf terialdurin the filtering process.`

Another o ject is to prevent a cloging of the filtering elements duringthe tering process,

Anvother object is to provide an apparatus .having various agitatingmeans comblned with lmproved heating means, whereby a large capacity isobtained with 8. small paratus, and to provide an apparatus pin whichthe actual volume of heated. oil is" relatively small and thereforecombines large capacitycwith-great safety. f Q;

As is wellknown, lubricatlu il,nwhex used in the. crank case ofa comiistion tor, soon becomes filledv with 'an -eircessof solid substances,including freacarbon and other non-lubricatingelements, and thefoilloses its elliciency for the purpose intended. To treat the oil forpurification, it is'ifneces-A sary to mix .theysame with clay,pulverize.

removed from thev oil, to accelerate the preheating step, to-acceleratethe filtering step, and to preventJ the clogging of the device.

My invention, stated in general terms, consists of anapparatusconstructed, arranged, and adapted or operation in substantially themanner. hereinafter." described and claimed.

v l The nature, scope an general features of `luy-invention willbe orefully understood by reference to the accompanying drawings, inwhich:

Figure 1 is a vertical and sectional e1evation', o f somewhatdiagrammatic character, showing an embodiment. of an apparatusfor-carrying out this-invention. Fig. 2 is a 1an view of the perforatedIter-'ing plate.

ig. 3 is a top plan view of the filterin casel o1` chamber, ndpreheating tank. 4 ig. 4 is a' detail v iew of the rotary agitator.4Referring 'to thedrawings 1n detail, the reheatintank 11, is mountedabove the llieatin'g c amber 12 which is supported by tandards 13,extending upwardly from the 14. f

j Vne'ath -thefheating chamber, I provide 'an an air pressurestorage-tank 15, and an air. compressor 16, which is operated by ancarbon land other elements which are to be im' electric .motor 17. Thetank 15 is supported by braces 18, connected to standards 13. The'filtercontainer 19, is supported bybrackets 20,on each side, anda bracket 21,and .is provided with a stuffing-box 22, in `which is mounted4 therotary shaft 23,l 'having on its lowerextremity, an agitator 24, and on'its upper extremity a worin gear- 'wheel 25, adapted to be driven bythe-worm pinion 26,"mo.unted' on .an electric motor 27. 'The agitator.24 may Abe'manually manlpulated, andsfor this purpose I provide-thecrank 28.' 'Shaft 23 .is journalled in' 'a bracket' bearing29, inbracket 30, Which also supports the motor 27. Within the heating chamber12, I provide a seriesof electric heaters 31, but gas heatvpurpose ofagitatingthe heated oil, I pro- -ersmay be employed if desired. For thewhereby the flow of the oilto the filtering be treated is then placed intank 11, and

elements may be regulated. A certain pres-` sure .within the container19 is desirablef I therefore provide a pipe 39, leading from air tank 15to the container 19, and having therein two control valves 40 and 41. Asafety valve 42, which may be set to'release the pressure at 130 poundsor over, is tapped into the pipe line 39,- between valves 40 and 41;this arrangement allowing the' ressure in the container to be controlledwithin desirable limits. L

Within the container, and in addition to the agitator 24, l provide aperforated steel plate 43, which supports a wirezsci'een 44, of finemesh, and above the screen. a felt fabric 45 through which= the'oil isfiltered, A pressure gauge 46 is provided for determining the pressureof the air within tank 15, but the desired pressure may be maintained byopening valve 40, whereupon the excess pressure is released by safetyvalve 42. i

i In use, the tank 15 is filled with air under pressure. The oil, orother material to the solution, anti other necessary ingredients areadded. Air pressure is released through .the perforated ringand agitatesthe contents of tank 11. Meanwhile the electric heaters are heating thecontents. material is then drawn oli into the container 19. The agitator24 is then revolved at a speed of approximately twentyv revolutions perminute. Air pressure is admitted to the container, and the urified oilpercolates through the felt fabric 45, and is drawn off through thevalve 47, at the bottom of cover 48, connected by hinge elements, withthe rrontainer. Studs 49, fixed to the cover, are provided withWing-nuts 50, for securing the cover in its closed position. To refillthe container 19, the valve 41 is closed, and the valve 38, opened. Fromtime to' time, the cover maybe turned to open position for the purposeof examining the filtering elements. The perforated plate 43, isconnected by a chain 51, with cover 48. f

From the foregoing description, it may be seen that I have provided asimple and t-iiicient apparatus for l'filtering'used oils, and forpurifying other mineral and animal oils and fats, and have described myinvention in connection with an illustrative foim of apparatus,materials, proportions,pi'essures, and arrangements, to the details ofwhich disclosure the invention is of course not to be limited. i

In the filtering of Various oils and fats, it,

has beenfound desirable to add the cla-y in varying quantities inaccordance with the nature of the substance' to be treated. This has atendency to form a deposit upon the A poi-tion of the 'and is secured inits adjusted position by the set screw 53. The thickness of the film ofclay upon the top of the filtering elements may therefore be regulated'in accordance with the` percentage of the clay added to the iinixtnrewithin the heating tank.

It desired, .lilterin elements of varying thickness may be emp oyed, andthe agitator may be adjusted ii accordance with such thickness forobtaining the best result with the greatest efiiciency.

What is 'claimed is:

1. In a filtering device, a container, a cover at the bottom of thecontainer, a perforated plate supported 4by the cover, a wire screensupported b the perforated plate, a thick pad of felt fa ric upon thewire screen, means for introducing the material into the top of thecontainer, means for preheating the material before it enters thecontainer,

a rotary agitator within the container, and

above the felt fabricr means for operating the agitator with a rotarymovementn an means for adjusting the agitator relatively to and from thefilterin elements.

2. Ina filtering "device, a container, a cover at the bottom ofthecontainer, a series of filtering elements supported by the cover inits closed osition, means for introducing the material to be filteredinto the top of the container, means for preheating the material beforeit Aenters the container, a rotary agitator within the container andabove the filtering elements, and means for adjusting the agitatorrelatively to and from the lfilterin elements.

3. In a ltering device,l a container, a cover at the bottom of thecontainer, a series of filtering elements supported by the cover -in itsclosed position, rotatable agitating elements within the container andabove the filtering elements, means for producing a automaticallyregulating the air pressure delivered to thecontainer operative when thepressure has reached a predetermined point, filtering elements at thebottom of tank includin the container, and means `for varying thethickness of deposits on the top filtering ele.-
